I have a filesystem that has lots of small files. Currently about 80% of inodes are used (I checked with df -i), however only 60% of disk space is used. How can I 'increase' the number of inodes? If ...

Tune2fs allows to change inode size from default (128 bytes on ext3, 256 bytes on ext4) to almost anything, but it should be power of two. What are the reasons for changing default inode size?

We're building a product that is likely to generate very large XFS volumes, and I'm trying to discover the scaling bottlenecks we're likely to run into given the architecture.
As we manipulate files ...

I want to manage a huge number of files on my server (say millions). It is needed to save files in two or three levels of folders to keep the number of files in each folder low. On the other hand, it ...

There are plenty of articles on the web detailing why you might not want to use Apache's default inode-mtime-size format for ETags (see e.g. here or here). All such articles recommend the same thing: ...

If I make a ext4 filesystem and add about 20% of extra inodes, how would this effect the inode count if later I extend the filesystem? Would the extended filesystem also automatically add an extra 20% ...
